I have another post out right now about the upgrade results. But I added the headers and did some light port work on the heads and the push rods were too long but I got 330/325rw. Injectors were maxed at 5,000 and wouldn't support the motor any more after 5,500. But with an extra two degrees across the table I picked up 5/5rw when I hooked the MAF back up that cost me 5/5rw. The correct push rods should be here today and I am going to put larger injectors in when I get my ported TBSS intake and ported LS3 TB. Still dynoing in 2nd. Check out my other post for full details.
